The overload trip setting is adjustable between 600 A and 4,000 A — that's a wide band, so it can be tuned to the actual load without swapping the breaker body. The interrupting ratings are serious: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 7.5 kA at 690 V. ## Built-in control and signalling This breaker ships with an undervoltage release (UVT) and a universal trigger (UNI) auxiliary release, plus two auxiliary switches (HP type). The UVT means the breaker trips automatically if control voltage drops — standard for safety disconnects on emergency-stop chains or undervoltage protection schemes. No communication module onboard (no PROFIBUS, no Modbus), so if you need remote trip data you'll wire the aux contacts into an I/O block. Panel cutout and mounting hole pattern match the SENTRON 3VA2 family.","metaTitle":"Siemens 3VA2340-6HL32-0LB0 SENTRON MCCB, 400 A, 3-Pole, Line","metaDescription":"Siemens 3VA2340-6HL32-0LB0 SENTRON molded case circuit breaker, 400 A continuous, 3-pole, line protection.
